FBI: North Korea Behind Sony Attacks

Confirming what had been speculated almost since the beginning, the FBI Friday confirmed that North Korea was responsible for the hack on Sony Pictures perpetrated by a group calling itself the Guardians of Peace, a cyberattack the White house has called a national security issue that will get a "proportional response."

"As a result of our investigation, and in close collaboration with other U.S. government departments and agencies, the FBI now has enough information to conclude that the North Korean government is responsible for these actions," the FBI announced.

"We are deeply concerned about the destructive nature of this attack on a private sector entity and the ordinary citizens who worked there. Further, North Korea’s attack on SPE reaffirms that cyber threats pose one of the gravest national security dangers to the United States," the FBI said.

“The FBI's announcement that North Korea is responsible for the attack on Sony Pictures is confirmation of what we suspected to be the case: that cyber terrorists, bent on wreaking havoc, have violated a major company to steal personal information, company secrets and threaten the American public. It is a despicable, criminal act," said Motion Picture Association of America chairman Chris Dodd.

MPAA has been criticized for not weighing in more forcefully on the attack and Sony's response, though he did address the attack at a press event in Washington earlier in the week.

"Disappointingly, that fact has been lost in a lot of the media coverage of this over the past few weeks," said Dodd in a statement. "This situation is larger than a movie’s release or the contents of someone’s private emails. This is about the fact that criminals were able to hack in and steal what has now been identified as many times the volume of all of the printed material in the Library of Congress and threaten the livelihoods of thousands of Americans who work in the film and television industry, as well as the millions who simply choose to go to the movies. The Internet is a powerful force for good and it is deplorable that it is being used as a weapon not just by common criminals, but also, sophisticated cyber terrorists. We cannot allow that front to be opened again on American corporations or the American people.”

The White House has said it takes the hack very seriously, considers it a national security issue-it stopped short of calling it a threat, and has said it is considering a range of options, and has not ruled out a counter cyber-attack.
